Detailed Description

Class to enforce ghost-cell based boundary conditions.

This class holds a domain's worth of boxghostbcs, one for each face. The user adds a BoxGhostBC-derived object for each face to enforce boundary conditions. If the solution is phi and the face normal direction is x, the boundary conditions at a face may often be expressed as A*phi + B*dphi/dx = C. The class derived from BoxGhostBC provides a function to to fill A B and C. DomainGhostBC calls this function and fills the ghost cells outside the domain appropriately.
